Application tiled April 17, 1903` Serial No. 153,055.

To r11/Z rif/1,0711, it 7mo/y concern.-

Be it known that I, OTTO E. HAUsBUao, a subject of" the Emperor ot Germany, and a resident ot New York, in the county et New York and State of New York, have invented certain new and useful improvements in Vatchmens Clocks, of which the loll/turing is a speciiication.

The object ot my invention is to produce a watchmans clock in which it will be practically impossible for a wrong record to be mad e or tor the working of the clock to be intertere-d with without detection.

My invention consists, inst, in providing in addition to the shoulders ordinarily vfound on recording-keys means for preventing any key vfrom being turned unless it is completely inserted, second, in means .ier guarding against a key being left in a registering p osition in a malicious eil'ort thus to stop the clock, and, third, in means for preventing the clock from being stopped even it a key be held in a registering position.

l carry the general organization into ei'liect by providing a key-cylinder into which the recording-keys Vlit and which revolves therewith, a spring-catch normally seating in slots in the inner end ot said cylinder and held out of said slots by the inner end of a recordingkey when said key is kept iully inserted, actuating-levers carrying pivoted registeringstyluses, and pointed actuating-cams on said levers.

The particular Viorm oiY clock used is not essential, my invention appertaining only to the registering apparatus, safety appliances therefor, and the specific or subordinate combinations the scopes eli which are defined in the claims.

Figure 1 is a front elevation oi my watchmans clock complete, the lid et the case being open. Fig. 2 is a 'fragmentary detail oi' the record-chal, on an enlarged scale, with record-marks thereon. Fig. E is a section on the line x of Fig, 1, the view being in an upward direction to Fig. 1. Fig. 4 is a section on the line 1/ 3/ et Fig. 3 viewed from the leiit. Fig. 5 is a section on the line e' 2 ol Fig. 4l, the view being in an upward direction. Fig. 6 is an enlarged detail et Fig. il, showing a key inserted and turned to recording position. Fig. 7 is an enlarged detail ot Fig. 3, with a key inserted and turned to recording position. Fig. S is the same as Fig. 6, but shows operation of the device when an attempt is made to make a wrong record by the l i l i l other, respectively, are holes 26 27.

use of a Vlialse key. Fig. 9 is a perspective view or the key-cylinder removed. Fig. 10 shows a modiiication in which the pointed cam is replaced by a small roller. Fig. 11 shows a set ot recording-keys on a slightlyenlarged scale, the handle portions being remove d All parts of the device are contained within the case 1, having the lid 2 and suspending ring 3, the said case being provided with a lock 4 and catch 5.

The record-dial G is operatively connected to the tin'ie-niovement 7, being removably retained in place by the washer 8, and passes between the greoved backing-block t) and the stylus-points 10. The block 9 carries a pointer Yl 1. actuating-levers 12 are Vfulcruma-cl on a pivot-pin 1.3, extending between the support 1-1 and the plate 15, the said plate and support being lixed to a base 16, Vforming the top frame-plate of the time-movement 7. Secured by one of its ends to the vase 16 is a plate -spring 17, normallybearing against all the levers 12 on their sides next to the said base, and on the opposite side ol" the said levers is a stop-pin 1S, supportedby the support 14 and the plate 15.

Pivoted to the free end oi each lever 12 is a stylus 19, having a lug 20, and on the lever 12 in. the path et the said lug is a stop-shoulder 21, against which the said lug normally rests. A spring 22, attached to each lever 12, presses against the side of each lug 2O on the side opposite to the shoulder 21. Each stylus 19 extends normally at right angles to its lever 12, passes through an opening 23 in the base 16, and terminates in a point 10 just out of contact with the dial VProiecting from each lever 12 in an opposite direction to the stylus 1Q is a double- 'liaced pointed. cam 24, the two Ylaces of the said cam being approximately alike and sloping in the direction oi the length of the said lever. Each lever 12, with its cam 24 and stylus 1S), is like any one of the others, and in the clock shown there are six o'i these levers. Fixed. to the base 16 opposite and parallel to the plate 15 is a block 25, andv in the block 25 and plate 15 opposite each Mounted to rotate in the holes 26 27 of the block 25 and plate 15 is a key-cylinder 2S, having reduced end portions 29 30. Extending the liull length or one side oi' the said. key-cylinder is a key-slot 31, and across its inner end and et a depth equal to the reduced portion IIO 30 are slots 32 33 at right angles to eachl other, the slot 32 registering with the keyslot 31. ln the block 25 is a key-slot 34, opening into the hole 26 and normally registering with the slot 31 in the cylinder 28, and in the case 1, registering with the hole 26 and slot 34, is an ordinary keyhole 35. ln the plate 15, extending out from the hole 27, are two opposite notches 36, which normally register with the slots 32 and 31, the cylinder 28 being mounted with its slotted end 3() journaled in the plate 15. Attached to the plate 15 by one of its ends is a ilat platespring 37, having at its other end a right-angular bent portion 38, which normally enters the slot 32 and the notches 36, the said bent portion of the spring 37 being wider than the slotted end 30 of the cylinder 28.

The bent-spring end 38 lies in the path oli the inner end 48 of any one of the keys 39 4() 41 42 43 44. The said keys have shoulders 45 46, which when the key is revolved are guided between the block 25 and plate 15. Each of the said keys also has a wing 47, a part ol" whose path is occupied by one of the cams 24.

In the operation of my device the dial 6 is given an. hour-hand motion by the timemovement 7. The clock is carried by the watchman and. the keys 39 40 41 42 43 44 are distributed to the respective stations, as is Wvhen one olz the said keys is inserted for the purpose of recording, the slot 34 allows the wing 47 and the shoulders 45 46 to pass `freely, but the shoulder 45 prevents the said key from turning be'liore it is fully inserted. Also as the said key is in the slot 31. it cannot turn without revolving the keycylinder 28, and the said cylinder is held stationary by the bent end 38 el the spring 37 being in the slot 32. When the said key is completely inserted, the shoulders 45 46 will turn between the block 25 and plate 15 and the spring end will have been lifted out ol" the slot 32 by the advancing key end 48, thus permitting the cylinder 28 to revolve with the said key. When tl ie said key is revolved, its wing 47 comes in contact with one of the cams 24, which thus moved upward in the direction of the base 16, and the stylus-point 10 is forced into the dial 6 and a record made. The grooved block 9 acts as a backing for the dial 6, so that the said dial cannot escape being punctured by the ad.- vancing stylus-point 10. A'lter a record is made the spring 17 returns the lever 12, carrying the cam 24 and stylus 19, to its normal position in contact with the stop-pin 18. The wings 47 on the respective keys 39 40, etc., are located at diil'erent places thereon, so as to operate di'l'l'erent ones of the styluses 19, thus indicating by the radial position of the mark on the dial 6 at which station any record has been made, the time at which it was made being indicated by the circumferential position of said. mark. It, as is commonly done, the key-shoulders 45 46 were depended upon alone without the locked key-cylinder 28, then by the use ol a false key 49 not having said shoulders a 'lalse record. could be made, because such a key could be turned without being liully inserted and its wing 47 caused to operate any one of the styluses 1. 9. lith my device the key must be kept fully inserted in order to be revolved. Should a false key, as 49, be held pressed iny till the slot 32 is passed and then withdrawn part way and. turned to actuate a stylus, then the catch 38 will fall into the slot 33, and il' the said 'false key be held in till slot is passed and then partly withdrawn then at the half-turn the said catch will snap into the slot 32, and in this latter event the false key 49 is held :fast in the clock and detection certain. The reason the false key 49 in the last-named position cannot be withdrawn is because its wing 47 is then between two o'l the cams 24, which prevent the said key from being pushed in to release the catch. 38. None ol the keys 39 40, &c., can be le'l't sticking in the clock in a recording position, because the wing 47 will slip o'l'l' of the point ol' the cam 24. In case one of the said proper keys 39 40, &c., be held in a recording position in an e'i'l'ort to stop the clock by restraining the movement of the dial 6 with the stylus-point 10 this result will not occur, because as the dial 6 is revolved. the stylus 19 will swing on its pivot in the direction of the dial movement and its point 1() thus be withd rawn from the said dial. yWhenever the said key may be released., the springI 22 returns the stylus 19 to its normal position on the lever 12 as the said lever is pulled away from the dial 6 by the spring 17.
